CORN-PLANTER.

SPECIFICATION forming part Of Letters Patent-NO. 438,058, dated October'7, 1890.

Application iled April 23, 1890. Serial No. 349,080. (No model.)

To all whom it may concern:

Be it knownthat I, KNUT BULAND, of Linn Grove, in the county of BuenaVista and State of Iowa, have invented a new and useful Improvement inCorn-Planters, of which the following is a full, clear, and exactdescription` r My invention relates to an improvement in corn-planters,and has for its object to provide an implement of simple and durableconstruction and one wherein the runners may be adj ustedvertically, asdesired, and in which the ordinary form of marker is dispensed with.

The invention consists in the novel construction and combination of theseveralparts, as will be hereinafter fully set forth, and pointed out inthe claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a central longitudinal section through the machine. Fig. 2is a plan View. Fig. 3 is a transverse section taken near the axle. Figais a detail sectional view illustrating the peculiar construction of thedropslide, and Fig: 5 is a detail perspective view of one of thesupporting-wheels of the machine.

The frame consists of two side pieces 10, connected by cross-bars 11,12, 13, 14, and 15, and the said frame thus constructed is mounted uponan axle 16, to the outer ends of which the supporting-wheels 17 arerigidly secured.

The drivers seat 17 f is preferably supported by attachment to the crossbars or beams l1 and 12, and to the extremities of a transverse rod orbar 18, attached to the forward portion of the frame, the forward endsof the runners 19 are pivoted, the said runners being located outside ofthe frame. The vertical standards 20- of the said runners, located atthe rear ends, are attached to a rod 21, extending across the frame.

The rod 21 has attached thereto, at ornear its center, one end of a link22, which link is pivoted at its other end to a lever 23, fulcrumed,preferably, upon the cross-bar 13, which lever is provided with anyapproved form of thumb-latch 24, adapted for attachment with a rack 25,as best shown in Fig. 1.

its under face, a lever 26 is centrally fulcrumed. Upon the axle 16 pins27 and 2S are secured, one of which extends upward and the otherdownward, and the said pins are so located that as the axle revolvesthey will alternately engage with the ends of the lever 26. The relativepositions of the pins to the lever are best illustrated in Fig. 3.

The seed-boxes 29 may be of any suitable or approved construction, andlikewise the. drop-bar 30 held to slide in the seed-boxes.` Thedrop-bar, however, is actuated in a peculiar manner, which consists inattaching chains 31 to pins 32, fast to the under side of the drop-bar,one at each side of its center, as shown in Fig. 2. These chains passover guide-pulleys 33,journaled, preferably, upon the cross-bar 14, andthe rear ends of the said chains are attached to the extremities of thelever 26, as best shown in Fig. 2, in which it will be observed that twochains only are ernployed.

The supporting-wheels 17 are also of peculiar construction, which isbest illustrated in Fig. 5, the said supporting-wheels being made upordinarily of two spaced metal tires 34, which are connected to the hub35 by spokes 36, the said spokes being bifurcated at their outer ends,as illustrated at 37, and at intervals upon the periphery of thesupportingwheels transverse plates 38,are attached, the said platesbeing so spaced that as the machine is drawn forward and the seeddropped one of the plates will press the earth down at each hill andmark the location thereof. Thus itwill be observed that by means of thissimple attachment to the wheels the usual cumbersome markers may bedispensed with.

In the operation of the machine the runners may be raised or lowered toproduce a deep or a shallow furrow and elevated quite high when it isnecessary to turn corners. As the machine advances and the axle isrotated, the pins 27 and 28, alternately engaging with the ends of thelever 26, act through the medium of the chains 31 upon the drop slide orbar 30 to regularly laterally reciprocate it.

I desire it to be distinctly understood that while specilic constructionhas been shown ICO and described I do not confine myself thereto, asother equivalent construction may be elnployed without departing fromthe spirit of the invention-as, for instance, the side bars of the framemay be connected by a greater or a less number of cross bars or beams,and the lever 23 may be differently located.

In order that the markers 38 may register properly with the markspreviously made upon the soil, I employ a device attached to theextremity of the frame of the machine, whereby the drive-wheels may beshifted from side to side as demanded. This device preferably consistsof a lever 40, pivoted at its inner end to about the center of the rearcross-bar 11 of the machine. To the said lever the upper end of apendent post 41 is pivoted, the said post being preferably pivoted tothe lever considerably nearer its inner than its outer end, and the saidlever, upon its under edge near the outer end, is provided with anattached hook 42. One end of a chain 43 is secured to the post 41 nearits lower end, the other or upper end of the chain being adapted forengagement with the hook 42.

In the operation of laterally adjusting the wheels the post 41 isdropped down to the position shown in positive lines'in Fig. 1 and itsbase made to rest upon the ground. The operator then bears down upon theouter end of the lever 40 until the rear portion of the frame of themachine is sufficiently elevated to cause the wheels to clear theground,and when this is accomplished the wheels are held in this position bytaking up the chain 43 and attaching one of its links to the hook 42.The wheels may now be carried either to the right or to the left bypushing upon the lever 40, the post 41 acting as a fulcrum. When themarker has registered properly with the last ldepression in the soil,the chain is loosened and the wheels suffered to drop in contact withthe ground. When this lifting attachment is not in use, it may becarried up to the position shown in dotted lines in Fig. 1 and securedin any suitable or approved manner to the drivers seat.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination, with the frame, the axle having pins27 28, the marking-Wheels, and the transverse seed-slide 30, of thetransverse centrally-pivoted lever 26, With its ends in the paths ofsaid pins, pulleys 33, mounted on the frame in rear of the seed-slide,and two chains 31, passing from the ends of the lever 26 forward aroundpulleys 33 and inward to the slide and secured thereto at 32 32,substantially as set forth.

KNUT BULAND.
